Field Validation

Field Validation

Validation ensures that data entered into a form is complete, accurate, and formatted correctly. Each field can be configured with validation rules.

How to Add Validation

  1. Open your form in the Form Editor.
  2. Select the field you want to validate.
  3. Go to the Validation tab in the field settings.
  4. Configure the rules you want to apply.

Common Validation Options

Required: Ensures the field cannot be left blank.

Minimum / Maximum Length: Set character limits (useful for text fields).

Minimum / Maximum Value: Set numeric limits (useful for number or currency fields).

Regular Expressions (Regex): Enforce specific formats (e.g., postal codes, custom IDs).

Email Validation: Ensures input matches a valid email format.

Phone Validation: Ensures input matches a valid phone number pattern.

Custom Validation: Write JavaScript-based validation for advanced rules. Example (require a value greater than 18):

Best Practices

  • Use basic required fields for must-have data.
  • Use regex or custom validation for compliance needs.
  • Keep rules as simple as possible to avoid frustrating users.
